LocalProp
Reference implementations of biologically plausible credit-assignment rules for deep networks.
PyTorchlearning rulestheory
LocalProp collects clean, benchmarked implementations of learning rules that avoid the biologically implausible weight transport of backpropagation — feedback alignment, target propagation, predictive coding, and our own local error signals from the NeurIPS 2025 paper.
Goals
- One consistent training loop so rules can be compared fairly.
- Benchmarks on vision and sequence tasks with logged compute budgets.
- A teaching resource: each rule has an annotated, minimal notebook.
If you are exploring how the brain might approximate gradient descent, this is a good place to start experimenting.
